It stands to reason that anyone would want to throw up if they had to try to top Idina Menzel's Oscar-winning version of "Let it Go" from Frozen.

And it turns out, that's exactly what happened to Lea Michele. While visiting Jimmy Kimmel Live on Wednesday, Michele, 28, admitted that her experience crooning the ballad – which was sung by her Glee mom Menzel, 43 – totally turned her stomach.

"I was super nervous. The day didn't start off so well," said Michele of the song she performed for the season 6 premiere. "I was singing, there was snow falling. I looked up trying to make it magical and beautiful and ended up choking on the snow and vomiting. They have it on slo-mo."

Glee is once again breaking new ground on broadcast television: Coach Shannon Beiste (Dot-Marie Jones) revealed on Friday's episode that she is transgender and will undergo sex reassignment surgery.

As Coach Beiste explained to Sam (Chord Overstreet) in simple terms, being transgender means "your outsides don't match how you feel you are on the inside. … This isn't about who I want to go to bed with – it's who I want to go to bed as."

Indeed, as Beiste reveals, she is still attracted to men, and that won't change following her reassignment surgery.

In an upcoming episode of Oprah: Where Are They Now on OWN, YouTube sensation and former Glee star Charice Pempengco gets personal, addressing gender identity questions head on.

"Basically, my soul is like male," Pempengco, 22, tells Oprah Winfrey after the talk show host asks about rumors of a gender transition. "But I'm not going to go through that stage where I change everything."

In recent months, the singer and actress, who officially came out as a lesbian last year, has gone through some significant appearance changes, causing some to speculate that aside from sexual orientation, a full gender transformation may be underway.
